DESCENTE to Under Armour clothing size
The short answer
DESCENTE S is Under Armour XXS by the two brands' own charts. 6 of 6 DESCENTE sizes land on a different label at Under Armour.
Both brands publish the body bust each size is cut for, so every row matches a bust, not a letter or a number.

What wearers say
